Benefits of technology

The present invention is a balance and gait perturbation system that includes a device and a data processing device. The device has one or more displaceable components that can be displaced at different positions and has one or more surfaces for receiving the person's limbs. The system can generate a stochastic signal to introduce a perturbation to the device and control its displacement position to affect the person's balance and gait. The system can also have secondary means for displacing the device in different directions and at different levels of intensity. The data processing device can generate a first and second perturbation signals and control the device to introduce different types of perturbations. The technical effects of the invention include improved testing and training for balance and gait disorders.

Problems solved by technology

However, the artificial nature of a typical environment for testing and / or training the balance and / or gait of a subject (e.g., a typical gait lab or clinician's office) makes it difficult to simulate the real-life conditions that are encountered by the subject.
Also, these artificial environments for balance and gait testing and / or training are unable to effectively simulate the uncertain nature of the stimuli encountered by subjects in real-life scenarios.
As such, these artificial balance gait testing and / or training environments are limited in their overall ability to effectively test and / or train subjects for the scenarios that are actually experienced by subjects in the their everyday lives.

Abstract

A balance and / or gait perturbation system is disclosed herein. The balance and / or gait perturbation system includes a balance and / or gait perturbation device and a data processing device. The balance and / or gait perturbation device includes one or more displaceable components configured to be displaced at a plurality of different positions, and having one or more surfaces for receiving one or more respective limbs of the person; and one or more first actuators coupled to the one or more displaceable components to adjust the displacement position of the one or more displaceable components. The data processing device is configured to generate a stochastic signal for introducing a perturbation to the one or more displaceable components, and to control the displacement position of the one or more displaceable components using the stochastic signal such that the one or more displaceable components perturb a balance and / or gait of the person.
